Proverbs 25:22
For thou shalt heap coals of fire upon his head, and the LORD shall reward thee.
For thou shall heap coals of fire upon his head,.... Not to increase his punishment and damnation, the more aggravated by kindness shown him; but to bring him by such means to a sense of former injuries, and to shame for them, repentance of them, and love of the person injured, and carefulness for the future of doing him any further wrong;
and the LORD shall reward thee: with good things, for all the good done to thine enemy, whether it has the desired effect on him or not; or whether he rewards thee or not; see Romans 12:20.
